Abstract
The utility model discloses a mechanical locking mechanism which is arranged in a cabinet. The front side of the inside of the cabinet is provided with a linkage slide plate, and the slide plate is provided with three natural locking positions, namely the closed working position, the break position, and the grounding overhaul position. The switchover among different positions is realized by moving the slide plate left and right. A rotating shaft of an isolating switch is connected with a connecting shaft sleeve via a pin shaft, and a spline of the connecting shaft sleeve is connected with an operating shaft sleeve, so the moment transmission is realized. The spline overcomes the flexible adjustment of the operating shaft sleeve angle, so an operator can complete the opening and closing operations of the switch by using the smallest force and the most convenient operating angle. The mechanical locking mechanism overcomes the defect of the large operating moment, and is simple in structure and easy to operate.
Description
Technical field
The utility model relates to a kind of isolating-switch locking mechanism, shrouding mechanical lock behind particularly a kind of switchgear.
Background technology
According to GB3906-2006 armored withdraw type switchgear operation continuity is required: the circuit breaker lock design must assurance can not get into charged interval by mistake; Can not close isolating switch during ground connection cutter ground connection; Isolating switch can not close a floodgate during ground connection cutter splice grafting ground; Can not close isolating switch by on-load.
The existing mechanical locking is to add a connecting lever through isolating switch, ground connection cutter operating axis; Drive connecting lever by the operating grip rotation and realize dividing closing operation the connecting lever on the moving isolating switch box ground connection cutter of screw rod top drawstring; But there is following problem: the bad adjustment of connecting lever; Operational torque is big, deciliter not in place, operating space requires defectives such as very big, often occurs stuck or phenomenon such as operation distortion.
The utility model content
The purpose of the utility model is to provide a kind of switchgear mechanically actuated operation blocking mechanism, have simple in structure, convenience operation.
In order to achieve the above object; The technical scheme of the utility model is achieved in that switchgear mechanically actuated operation blocking mechanism; Be installed in the cabinet; It is characterized in that the inner operating mechanism of cabinet changes spline into by original screw rod connection and connects, and has the connecting lever operation to change the straight-bar operation into; Locking between the operation of isolating switch or on-load switch and operating mechanism realizes mutual locking through the diverse location hole on the anterior chain slide plate of cabinet, and the locking of cabinet door and operating mechanism meanwhile is that spring draws stretching out of pin-and-hole to withdraw and the hook of cabinet door is realized below slide plate is when the diverse location.
A kind of mechanical lock is characterized in that, comprises isolating switch rotating shaft, connecting bushing, operation axle sleeve, chain slide plate, locking stage clip, lockweight; The isolating switch rotating shaft is connected with pin with connecting bushing, and connecting bushing and operating axis are applied mechanically spline fitted and transmitted operational torque; The locking of door is that locking stage clip and the lockweight below chain slide plate realized locking.
Owing to adopted technique scheme, the utility model to overcome the big defective of operational torque, had simple in structure, convenience operation.
Description of drawings
Fig. 1 is the structure principle chart of the utility model;
Wherein: cabinet 1, operation axle sleeve 2, operating grip 3, chain slide plate 4, locking stage clip 5, lockweight 6, Qianmen 7, isolating switch 8, connecting bushing 9.
Embodiment
Be described in detail below in conjunction with the structural principle and the operation principle of accompanying drawing the utility model.
Like Fig. 1, shrouding mechanical lock behind the switchgear is installed in the cabinet 1, and cabinet 1 inner preceding front is provided with chain slide plate 4, and slide plate has three natural locked position of couplers: " closure ' service position, " disconnection " position, " ground connection " maintenance position.Slide plate is realized the conversion between the diverse location through move left and right.The rotating shaft of isolating switch 8 connects through connecting bushing 9 usefulness bearing pins; Spline on the connecting bushing 9 is connected with operation axle sleeve 2; The realization operational torque transmits; Spline has overcome the flexible adjustment of operation axle sleeve angle, be operating personnel with minimum power, the work angle of most convenient realizes the operation that deciliter waits of switch.
The operation principle of the utility model is: the blocking mechanism of the utility model is to be put into " closure " service position through chain slide plate 4, can only disconnecting switch operation 8 deciliter; Chain slide plate 4 can move on to " disconnection " position when having only isolating switch 8 to be in " disconnection " state; At this moment isolating switch 8 box earthed switches all can not be operated; If with chain slide plate 4 " ground connection " position like this can the operational grounding switch deciliter, as long as when the ground connection cutter closes after, locking stage clip 5 is gone back by lockweight 6 compressions and Qianmen 7 solves locking; Door can be opened and overhaul, and has realized preventing that mistake from getting into the band point at interval.Otherwise operation also realizes sending electric step.Realization is simple to operate clear and definite like this, and is convenient and safe reliable, obtains checking in actual use.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the execution mode of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation and changes.Here can't give exhaustive to all execution modes.Conspicuous variation that every technical scheme that belongs to the utility model is amplified out or change still are in the row of the protection range of the utility model.
